Based on your screenshot, auto-dedupe is correctly enabled on the "Company Domain" column. However, auto-dedupe only triggers when new rows are added or existing rows are edited. [1]
Since you're using lookups and write to table operations, try these solutions:
1. Enable auto-update on Table D
Click the table name → Select "Enable auto-update"
This ensures all columns run when rows are added/edited [2]
2. Force run the write to table column
If the write to table function isn't processing correctly, use Force Run in table settings
Or delete the column, create a fresh one, and re-map your data
3. Verify your write to table configuration
Ensure it's set to add new rows (not just update existing cells) [3]
If the issue persists after trying these steps, click "Talk to a person" for human assistance with your specific workbook.

Your screenshot shows auto-dedupe is working correctly — 174 duplicate records have been automatically deleted, including multiple iproov.com entries. [1]
Auto-dedupe monitors your specified column and removes duplicates when new rows are added or existing rows are edited. The deduplication history confirms this is functioning as designed.
If you're experiencing a different issue with your write to table workflow, ensure:
Auto-update is enabled on Table D so columns run when rows are added/edited [2]
Your write to table is configured to add new rows rather than update existing cells
What specific behavior are you expecting that isn't happening?

Hey Vishal, happy to help! Could you let me know a bit about what is going wrong. From what I see this functionality seems to be working as intended.
